GOLF

Application filed May 5,

To all whom it may concern:

Be it known that I, FRANK L. SLAZENGER, a citizen of United States,residing at New York city, in the county of New York and State of NewYork, haveinvented certain new and useful Improvements in Golf Clubs, ofwhich the following is a specification, reference being had therein tothe accompanying drawing.

The present invention relates to golf clubs, and aims to provide noveland improved means for anchoring or securing a metal shaft in the clubhead, in order to provide for a secure and rigid connection and one thatwill, if the glue or cement loosens, still remain tight to prevent thehead flying off the shaft.

Resilient tubular metal shafts are rapidly becoming the vogue, and thedemand for them is increasing. One objection to the use of a metal shaftis the difliculty in securing the shaft to the head so as to-withstandthe severe shocks and strains to which the club is subjected in use. Thepresent invention contemplates the provision of simple and effectivemeans for securing a'metal shaft in the head, and even though glue orcement used may loosen, the head will remain tightly on the shaft, theimpact of the head with the ball servingto tighten the head on theshaft.

With the foregoing and other objects in .view, which will be apparent asthe description proceeds,-the invention resides in the construction andarrangement of parts, as hereinafter described and claimed, it beingunderstood that changes can be made 2 within the scope of what isclaimed, without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawing, wherein Figure1 is a front view of the head end of a golf club embodying theimprovements. Fig. 2 is a median vertical section through the jointbetween the head and shaft,

The head 7 is of wood, as usual, and may be of any suitable size andshape, being provided with the inclined shank 8, and the striking face.9. The shank 8 has a tapered bore or socket 10 extending to a pointbehind the heel end of the face 9 to receive the shaft 11. The shaft 11is of steel or other suitable metal, so as to be resilient, and istubular.

In order to secure the shaft in the head,

a sleeve 12 of aluminum or other suitable metal or alloy is cast on thelower terminal portion of the shaft 11, so as to be intimately unitedwith the shaft substantially integral therewith. The sleeve 12 istapered slightly from a point near its upper end to its lower end toconform to the downward taper of the socket 10, so that said sleeve willwedge tightly into the socket. The upper terminal 13 of the sleeve istapered off upwardly so as to provide a neat finish.

The lower terminal portion of the sleeve 12 is formed with, ascrew-thread 14 so as to screw into the wood of the head within thelower portion of the socket 10. The

' sleeve 12 projects sufiiciently from the shank 8 so that it may beengaged by a wrench,

vise or other implement when securing the sleeve 12 into the head. Glueor cement is used between the sleeve 12 and head, as usual, in order toobtain adhesion between the head and shank.

The screw-thread 14: extends in such a i direction that if the glue orcement between the sleeve 12 and shank 8 becomes loose, the tendency forthe head' 7 to rotate around the shank due to the impact of the headagainst the golf ball, will screw the head tighter on the shank. Thus,the eater the impact the tighter will the head "screwed on the shaft.For a right hand clubthe screw-thread 14 is left-handed, and for a lefthand club the screw-thread is righthanded. The screw thread 14-. ispreferably of V-shape with its convolutions spaced as to readily screwinto the wood, as well as to provide suflicient width of thescrew-thread of the head so as to obtain the firm anchoring of the shaftin the head without danger of the screw-thread of the head tearingloose. It will also be noted that the sleeve 12 being tapered will wedgetighter in the head the further the head and shaft are screwed together.

Having-thus described the invention, what;

is claimed as new is 1. A golf club comprising a head having a shankprovided with a tapered socket, a tubular metal shaft, and a metalsleeve cast on the lower terminal of said shaft, said sleeve beingtapered downwardly to wedge tightly into said socket andhavingscrewthreads en aging the head.

2. A go club comprising a head having a shank provided with a taperedsocket, a

tubular metal shaft, and a metal sleeve cast llU on the lower terminalof said shaft, said sleeve being tapered downwardly to Wedge tightlyinto said socket and having a screwthread at its lower end engaging thehead,

- the upper portion of the sleeve projecting from the shank.

3. A golf club comprising a head having a shank provided with a taperedsocket, a tubular metal shaft, and a metal sleeve cast on the lowerterminal of the shaft and screw- 1 threaded in said socket, said sleevebeing tapered downwardly to wedge tightly into said socket, thescrew-threads extending in a direction to tighten the head on the sleeve'due to impact of the head with a ball. 15

In testimony whereof I hereunto'aflix my signature.
